For David Robinson: The new edition sounds interesting. Would the
publisher agree to price it competively for the classroom market? I
like to use 5 or 6 books for each course as a minimum. When books
are in the $30 each range, my students scream. ( Incidentally, they
have no problem paying $60 or $70 for a Chemistry text!). $225 for
a slide collection seems reasonable if they are of good quality. I
am concerned that they are over 15 years old as you indicate in your
e-mail. Is there a contemporay section or do you plan to update the
slide collection?
